I am writing a resume. I want to specify that I started my education in 2009 and as of now I am at the 4th grade (in other words, still learning), so how should I specify that in resume: 2009 - present 2009 till now Any suggestions?.
On resumes, the most common way to indicate that a period is ongoing is either 2009 present or 2009 to present The en dash is the preferred punctuation. Many word processors replace a double hyphen with an en dash once the next word is typed.
